Barrier Lake

Barrier Lake, formerly called Stony Lake, is a small lake in New Westminster Land District of southwestern British Columbia, Canada. It is located west of Garibaldi Lake in Garibaldi Provincial Park. The name of the lake was adopted on September 2, 1930, for its association with The Barrier, a volcanic dam retaining the Garibaldi Lake system. Barrier Lake has a mean annual discharge of 10.44 m3/s (369 cu ft/s). Barrier Lake is an expansion of Rubble Creek, which flows northwest into the Cheakamus River. This stream follows a subterranean channel under The Barrier at Lesser Garibaldi Lake just to the southeast, but at times of exceptionally high water, a part of it flows over the surface of the volcanic dam to Barrier Lake. Rubble Creek then flows through an outlet at the southwestern end of Barrier Lake where it flows over the headwall of The Barrier into the lower valley. Barrier Lake lies within a depression that straddles on a contact between andesitic lava of The Barrier and sedimentary rocks forming the northern side of upper Rubble Creek valley. The sedimentary rocks are of Cretaceous age, whereas the andesitic lava is of Late Pleistocene age. About 13,000 years ago, the andesitic lava was erupted from Clinker Peak and flowed into Rubble Creek valley where it ponded and cooled against residual glacial ice to form The Barrier. The lava lobe damming the southern end of Barrier Lake apparently formed when molten lava broke through the northern levee of The Barrier lava flow. Because the lake is in close proximity to the unstable headwall of The Barrier, it has been suggested that Barrier Lake, along with Lesser Garibaldi Lake, could be released in the event of a catastrophic collapse. If these lakes were to be released, they could initiate a debris flow capable of blocking the Cheakamus River or running out into Daisy Lake. However, the probability of this happening is considered to be very low.

Mount Price (British Columbia)
Mount Price (British Columbia)

Mount Price is a small stratovolcano in the Garibaldi Ranges of the Pacific Ranges in southwestern British Columbia, Canada. It has an elevation of 2,049 metres (6,722 feet) and rises above the surrounding landscape on the western side of Garibaldi Lake in New Westminster Land District. The mountain contains a number of subfeatures, including Clinker Peak on its western flank, which was the source of two thick lava flows between 15,000 and 8,000 years ago that ponded against glacial ice. These lava flows are structurally unstable, having produced large landslides as recently as the 1850s. A large provincial park surrounds Mount Price and other volcanoes in its vicinity. It lies within an ecological region that surrounds much of the Pacific Ranges. Mount Price is associated with a small group of volcanoes called the Garibaldi Lake volcanic field. This forms part of the larger Garibaldi Volcanic Belt, a north−south trending volcanic zone that represents a portion of the Canadian Cascade Arc. Mount Price began its formation 1.2 million years ago and continued intermittently until sometime in the last 15,000 years. Although the mountain is not known to have been volcanically active for thousands of years, it could erupt again, which would potentially endanger the nearby populace. If this were to happen, relief efforts could be organized by teams such as the Interagency Volcanic Event Notification Plan who are prepared to notify people threatened by volcanic eruptions in Canada.
